That's my plan, already use it for a custom wind generator so that is my staring point. Need to see what the sdk offers.

Hi all,

I know this might be a very niche market but could the inclusion of the FeelReal be included? I should be getting the SDK kit through soon so I can have a play with it and see how it all works, I signed an NDA so I can't distribute but ask them at [email protected] if you want to give it a go. If I get anything working well later down the line I can share it with you all.

Thanks,
Gavin

My bad, I had PP turned on already. Yes, the trees to the left are as you said, the ones on the right are fine.`

Quote from emiljensen2 :It seems on the autocross track there's trees, these rotate with head motion and look different in each eye when parallel projection is disabled.

I have gave this a try and didn't notice anything out of the ordinary. I did note they seem to be blowing in the wind and twisting slightly but nothing excessive, they all looked OK to me from a distance (I didn't have the lighthouse enabled at the time on this test)

Hi,

All confirmed working fine now.
Thanks

Yes, that does sound like it, let me know when its done and I will make time to test it (Pimax is now in the F1 car so its not as easy to test as before)

Quote from Gavin Kay :I haven't had any issues with fps on anything yet but I haven't tried anything really demanding - NoLimits2 demo is probably the most taxing but using brainwarp it runs very smoothly.

I have tested with default settings on a 770GTX, kept getting total crashes/freezes/green screen. After swapping to a 3GB 1060 yesterday it ran perfectly on default settings for a good 40 minutes with very little noticeable frame rate drop.

Small bug to report, when doing a replay the menu is fine but looks like the fix hasn't affected the actual replay itself and still needs PP activated to view so you get a strange sort of double image over a perfect menu.

Quote from loopingz :Thanks for the feedback! Well I run a 1080 + decent cpu. So I guess it is ok for pimax 8k but maybe only for lfs...

While I have you here, can I be cheeky and ask the possibility of including 5.1/4.1 surround sound at some point? It has been asked about by others but not that often, my F1 car has 4 speakers and a sub but LFS only outputs stereo sound, I only found out about this when all had been installed.

The new DLL works and shows the IPD at the top left now.

Still not sure about my issue I removed on the last post - I did get the issue first time but thought I'd better try again with PP enabled. I run it as a double check without PP for the second time, ready to get a baseline, enable and try again but it worked so I removed the problem. It has been fine since then so it might have just been my eyes!

No problem with the tests, thanks for the great game.

I run on an i7 4790 with a 1080 (my 1080ti doesn't fit in the case). Using the Pimax brainwarp you can restrict the fps to 60 but I have left it at the default of 80. All settings are maxed both in the nVidia control panel, Pimax PiTool, SteamVR and LFS and I don't get any drops or stuttering at all. Even with PP turned on I there are no issues, it really is a testament to the programming that they can get such good visual quality with so little processing.

I plan to run it on a 770gtx so we will see how that gets on later this week, I am not expecting much but I do have a spare 1080ti as well as a 1060 to try if needed.

That would be great, I should be able to try it about 8pm tonight.

Yes, I can confirm its working fine.

Running with your updated DLLs I Switched ON the option for Compatible with Parallel Projections and then closed SteamVR.

When launching LFS Steam VR starts up and all is fine. I guess as I only really have this that needs PP switched on I was disabling it to go back to the other games before restarting the PC or Steam.

I do agree that the image looks cleaner without PP but I only have one eye to go with on that and from what I have read elsewhere it will be much more efficient without PP.
https://forum.pimaxvr.com/t/psa-parallel-projection-makes-things-blurry-on-5k-8k-dont-use-if-the-game-doesnt-require-it/11564
Saying that though, I have my one running at maximum quality for everything and still get 80fps easily although I do notice artifacts in the sky, black polygon flickering now and again.

Parallel Projection is set in the Pimax software, PiTool under the Settings->Brainwarp

I haven't found anything else that needs PP enabled yet but they have a list here
https://docs.google.com/spreadsheets/d/11ljKyF0eMgY3qqZWjVVBvI0brfv9IxocXjroYtJyTlY/edit#gid=0

If you are in the Kent area (Chatham) of the UK feel free to drop me a PM and do a bit of testing.



Thanks

Needed to restart SteamVR for it to work, didn't know that before!

After doing this I think its about perfect for me, how about you emiljensen2?

Hi,
Thanks for the speedy reply, I will give this a go in a couple of hours and post the results.

A small update from me, if you check here
https://www.reddit.com/r/Vive/comments/727f7q/a_recent_update_to_openvrs_driver_interface/
it seems like the same issue, i.e. rather than 2 independent perspectives it views from one point and adjusts the image left and right, this would explain why its OK at close range.

I have just posed this question to the LFS team citing this post so hopefully they will help out. I don't think its PP as my understanding is it swaps the left and right images over. Adjusting the IPD on the bottom of the headset works but it cannot go low enough to fix the problem, maybe because the FOV is so great!

Hi emiljensen2

I received my Pimax 8k today and hoped to use it exclusively with LFS but have the same issue as you, did you get it resolved or find a workaround?

Thanks
